HYDRODENITROGENATION OF 2-METHYL QUINOLINE - EFFECT OF STERIC HINDRANCE IN LIQUID PHASE CATALYTIC HYDROGENATION

Abstract:

Hydrodenitrognation (HDN) of 2-methyl quinoline (quinaldine) and quinoline in liquid phase on S-NiMo/a-Al2O3 catalyst was carried out in a batch reactor at 3.0 - 10.0 MPa and 130 - 360oC in Poly alpha-olefin solvent. Hydrogenolysis and Hydrogenation results in formation of products such as 1,2,3,4-treta hydro Quinaldine (1-THQ), 5,6,7,8-terta hydro Quinaldine (5-THQ), Deca hydro Quinaldine (DHQ), Butyl cyclohexane (BCH), Butyl cyclo hexene (BCHE) and butyl benzene (BB). Under studied condition, amine rings of quinaldine was rapidly hydrogenated and it forms relevant quasi equilibrium with 1,2,3,4-treta hydro quinaldine (1-THQ), 5,6,7,8-terta hydro quinaldine(5-THQ) and Deca hydro quinaldine (DHQ). The quinaldine reaction path either 1-THQ or 5-THQ indicated dependent of temperature and independent of partial pressure. Over which amine adsorption on metal sites reduced due to steric hindrance of methyl-group adjacent to N-bonding and increases the rate of intermediate formation through benzene ring hydrogenation. Distinguished HDN hydrogenolysis mechanism of quinaldine and its intermediate compounds were studied and compared with quinoline HDN. Thus, 5-THQ to DHQ and C-N cleavage identified as rate limiting step through steric hindrance HDN mechanism.
